' Application filed october 10.1907.` serai No. 396,814.

To all whom it may concern:

Be it known that I, TEUMAN PANGBURN, a citizen of the United States, residing at Alma, in the county of Allegany and State of New York, have invented a new and useful IrIame-Fastener, of which the following is a specification.

This invention relates to .hame fasteners.

The object of the invention is to provide a novel and thoroughly eiiicient hame fastener that may be readily connected with and disconnected from the hames, and in which the hames may be firmly clamped about the collar and secured against danger of accidental separation therefrom.

Vith the above and other objects in view as will appear as the nature of the invention is better understood, the same consists in the novel construction and combinationof parts of a hame fastener as will be hereinafter fully described and claimed. f

In the accompanying drawings, forming a part of this specification, and in which like characters` of reference indicate corresponding parts:` Figure 1 is a view in elevation of a pair of hames showing an improved fastener, constituting the present invention applied thereto. Fig. 2 is a top plan view partly in section. Fig. 3 is an edge view".

ig. 4 is a bottom plan view. Fig. 5 is an end view partly in section of the sheath. l

Referring to the drawings, II designates a pair of hames, of the usual or any preferred construction, the lower ends of which carry loops or eyes E to be engaged by the members of the hame fastener.

The hame fastener, shown in detail in Figs. 2, 3 and 4, comprises av sheath or body, designated generally 1, and a rack bar 2 to coact with locking mechanism in the sheath to hold the hames positioned upon the collar.

The sheath comprises a back plate 3, which, as shown in Fig. 3 is longitudinally bowed or curved to conform to the contour of the collar, and is provided at one end with a hook 4 to engage the eye of one of the hame members. Secured to the back plate, and properly spaced therefrom, is a front plate 5 provided adjacent to one edge with a pair of longitudinally disposed ribs 6 and 7, form- 3, are commensuratev in length with the p ate yand are approximately triangular in form, although this latter feature is not absolutely essential. The front and back plates are held positively spaced apart along one edge by a flange 8 forming a continuation of the keeper 6 and along the other edge by spacers 9 and 9a, which `latter may be integral either with the back plate or with the-front plate, as may be preferred. Pivoted between the keepers 6 `and 7 is a tensioning lever com-` prising an arm 10 and a segmental toothed head11 which latter is adapted to project 4correspond to the curvature of the sheath and is provided with two sets of ratchet teeth 14 and 15, the former of which are adapted to .be engaged by the teeth on the head of the tensioning lever, and the latter by a dog 16, pivoted at 17 between the front and back plates, as clearly shown in Fig. 3.- This dog is somewhat greater in length than the distances between the spacers 9 and 9*l and its freeendlS is adapted to engage with the spacer 9a, whereby, to limit the outward movement of the dog relatively to the sheath.

In order to cause thev toe 20 of the dog to.

interlock with the ratchet teeth 15, a leaf spring 21 is provided, one end of which is seated in a kerfl in the dog, and the other end in a kerf in the spacer 9a; Adjacent to the free end 18 of the dog', the back plate is provided with a thumb notch 22 by which to permit free. depression of thedo to throw its toe out of engagement with t e ratchet teeth 15. The outer end of the rack bar is provided with a hook 23 to engage one of the eyes E of the hames.

It will be observed by reference to Fig. 4,

'that the two sets of ratchet teeth 14 and 15 are disposed at right angles to each other, and this arrangement will facilitate an independent manipulation of the dog and of the tensioning'lever without one interfering with4 the other.

In the use of the fastener, when its members have been properly assembled with the hames, the rack bar is inserted within the channel 13 and the hame members are then drawn as tightly together as possible by manual strength. The tensioning lever is then operated and will result in exerting such longitudinal draft upon the rack bar as to cause it to be forced one inch further within the channel, and this will result in imparting the requisite draft upon the hames to cause them to remain positively assembled With the collar.

When it is desired to detach the hames it will only be necessary to press the free end 18 of the dog, whereupon the toe 20 will be freed fromengagement with the ratchet teeth 15, and upon outward draft being applied to the hame member carryingI the rack bar 2, the tensioning lever will be thrown to the position shown in Fig. 1, whereupon the two hame-fastening members may readily be disconnected.

It will be seen from the foregoing description that although the improvements herein defined are simple in character that they will be thoroughly efficient for the purpose designed and will be positive in retaining the hame members in locked relation.

Having thus fully described the invention what is claimed as new and is desired to be secured by Letters-Patent is z- 1. A llame fastener comprising a sheath, a double toothed rack bar longitudinally movable within the sheath, a locking dog for engaging one set of teeth of the rack bar, and a tensioning lever for engaging the other set of teeth.

2. A hame fastener comprising a sheath l rovided with a longitudinal channel, a double toothed rack bar movable within the channel, and a locking dog and a tensioning lever to coact with the two sets of teeth of the rack bar.

3. A hame fastener comprising a sheath embodying a front and aback plate properly spaced apart, spaced keepers carried by the back plate, a tensioningleyer pivoted between the keepers and having a toothed segmental head projecting throu h the back plate, a dog pivotally mounten? between the plates, and a doubletoothed rack bar movable between the plates and adapted to be engaged by the dog and by the tensioning lever.

In testimony that I claim the foregoing as my own, I have hereto afliXed my signature in the presence of two witnesses.
